<p>PURPOSE: To extend the water circulating range of a float fountain for purification while enhancing water purifying effect by floating the fountain on water and driving an underwater pump to suck the water at the position separated from a casing by a proper distance in a horizontal direction from the end of a conduit to eject the water to a casing. CONSTITUTION: A float fountain 11 for purification is constituted by loading a casing 12 composed of an air impermeable material with a conduit 14, a float 5 and an underwater pump 4 and floated on basin water by the buoyancy of the float 5. When the underwater pump 4 is driven, basin water is sucked from the end 14b separated from the casing 12 by a proper distance in a horizontal direction of the conduit 14. The sucked water flows in the casing 12 from an intake port 13 and passes through a filter 9 to be sucked into the underwater pump 4 through a suction port 6 and passes through an emitting pipe 7 and a jet part 8 to be ejected from jet nozzles 3.</p> |
